Solution1.
Answer (a)
Explanation: Here Z =1, Y =2 ……………, A =1.
1st C → F → I → L → O.
Difference is 2.
2nd Number is sum of the letter placed in reversed alphabetical order i.e., c = 24
So, 4+2 =6, and so on in the same pattern.
Solution2.
Answer (c)
Explanation:
C→H→M→R→W, there is simple addition of five letters.
8→12→16→20→24. The numeric series increases in the order C = 3 + 5, H = 8 + 4,
M = 13 +3, R = 18 + 2 = 20, w = 23 + 1 =24.
Solution3.
Answer (c)
Explanation:
1st term, O → R → U → X → A , Adding 3 in each previous alphabet.
2nd term, 1 → 2 → 6 → 21 → 88 = 1, (1×1)+1,(2×2)+2,(6×3) + 3, (21×4) + 4.
3rd term, F → H → J → L → N, Adding 2 in the previous alphabet.
Solution4.
Answer (a)
Explanation: 1st number in each 13 → 17 → 21 → 25 → 29 is increased by 4.
2nd alphabet L → D → V → N → F. Subtracting 8 from previous alphabet.
3rd numeric value is multiplication of two numbers of first, i.e. 13 = 3×1= 3, 17= 1×1=7, and so on.
Solution5.
Answer (b)
Explanation:
Solution7.
Answer (c)
Explanation: As M=J≥D we can say that either M=D or N>D
Solution8.
Answer (d)
Explanation: From the statement we get, K≥D≤N>B. Hence neither I nor II is true.
Solution9.
Answer (e)
Explanation: From the statement we get W≤T<X=J, hence J<W and T<J are definitely true.
Solution10.
Answer (b)
Explanation: From the given statement we get D=N>B <L, hence D>B is definitely true but L>D is false.
Solution11.
Answer (b)
Explanation: From the statement we get C≤D=N<F, thus C<N is false as C can also be equal to N but F>C is definitely true.
